InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Hello Guys,

Our cache application uses REST web services and handles single API request perfectly with response (response status and related data). But sometimes user sends multiple requests to the same API simultaneously ( ie, without waiting for the first to respond ), where one request will succeed (not necessarily the first) and the others will fail.

So, I need to handle the requests one by one after completing and sending the response for first request in the queue then process the next request and so on.

Hi,

The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.

It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.

Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

Hi community members!

Recently a customer ask me about a problem that detected when they were trying to send a post call to an external HTTP service, this service has changed and now it redirects to another URL, so they have setted to true the FollowRedirect parameter (setted to false for POST calls by default), what is the problem? They are sending a custom header in the post call and after the redirection this value is deleted.

Hi all,

I'm very new to this ecosystem so please bear with me:

I've startted learning online and have installed everything I need. I have VS code and I have most definitely installed the pack (3 packages) needed for working on it with ObjectScript. Even though this is the case I'm running into 2 problems:

1. when I type "class" I only get 4 option for auto complete. no "class with multiple inheritances" or anything of the sort. In fact, no Class at all, only ClassMethod. ClassResponse etc.

Hi Community,

Can anyone point me to the docs that show how to add automatic class documentation for the arguments used in a method call? I can auto document the class, methods, properties etc. with the "///" but can't figure out how to get the nice argument documentation for the arguments used when calling a method.

Thanks in advance

Hello!

I would like to find all classes not up to date in a namespace programmatically.

With IRIS Studio, we can see the single "+", but I don't know how to do that with a script.

Set sql = "SELECT ID, Name FROM %Dictionary.ClassDefinition WHERE NOT ID %STARTSWITH ?"
Set params($Increment(params)) = "%"
Set tResult = ##class(%SQL.Statement).%ExecDirect(, sql, params...)

If (tResult.%SQLCODE'=0)&&(tResult.%SQLCODE'=100) Set sc = $$$ERROR($$$SQLError, tResult.%SQLCODE, tResult.%Message) Quit sc

While tResult.%Next() {
    // if class not up to date ??
}

Using VECTOR_COSINE() in SQL query to perform a text similarity search on existing embeddings in a %VECTOR column.

Hello,

How can I send a request via a SOCKS5 proxy in IRIS, using, for example, EnsLib.REST.Operation?

Background

I need to access APIs inside my corporate network, to which I don't have direct access from my home office. I've set up a SOCKS5 proxy via SSH on my host machine like this:

ssh -D 9999 server.corporate.com

I can then make requests with curl to the APIs I need:

Hello!

I wonder if anyone has a smart idea to extract an XML fragment inside a text document (incoming from a stream)?

The XML fragment is surrounded by plain text.

Example:

text...........
text...........
<?xml version="1.0" encoding="UTF-8 ?>
<Start>
...etc
</Start>
text...........
text...........

The XML is not represented by any class or object in the Namespace.

The XML can look different from time to time

I'm wondering what the best practice is for handling %Status values within the terminal. 
1. set tSC=...
    do $SYSTEM.Status.DisplayError(tSC)
 
2. set tSC=...
   zwrite tSC

3. An alternative?

Is there a meaningful difference between the two? Should one be used over the other for any reason? Should something else be used?

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

Is there a way to exclude specific members from a class when exporting to an XML or UDL file? Bonus question: is there a way to import from that file without overwriting those members that were excluded?

The use case is to export an interoperability production class without the ProductionDefinition XDATA. We plan to source control the production items through the Ensemble Deployment Manager, but we still need to export any custom code in the class definition itself.

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

We are using the IRIS cloud. and I am working on a DTL .

so the source side timestamp is local time for example 20240110134740, I know it is a local time. so the requirement is I need to append the UTC at the end, like -0400 or -0500 depending on if it is daylight saving time.

so is there function to return if current day is at daylight saving time, so I can decide if I need to append the -400 or -500? or a function to return the current UTC by location?
